Question: Question: What was the name of Stephen's paternal grandfather? Passage:Stephen Tvrtko I (, Стефан/Стјепан Твртко; 1338 – 10 March 1391) was the first King of Bosnia. A member of the House of Kotromanić, he succeeded his uncle Stephen II as Ban of Bosnia in 1353. As he was a minor at the time, Tvrtko's father, Vladislav, briefly ruled as regent, followed by Tvrtko's mother, Jelena. Early in his personal rule, Tvrtko quarreled with his country's Roman Catholic clergy, but later enjoyed cordial relations with all the religious communities in his realm. After initial difficulties – the loss of large parts of Bosnia to his overlord, King Louis I of Hungary, and being briefly deposed by his magnates – Tvrtko's power grew considerably. He conquered some remnants of the neighbouring Serbian Empire in 1373, after the death of its last ruler and his distant relative, Uroš the Weak. In 1377, he had himself crowned King of Bosnia and of Serbia, claiming to be the heir of Serbia's extinct Nemanjić dynasty.

Question: Question: What's an instrument strongly associated with the traditional music found in the album's sixth track? Passage:It opens with two club-driven tracks: an interlude titled "Bridge to the Sky", and the promotional titular song. "Disco-munication" is the second interlude on the album, blending "sophisticated" electric guitars with electronic music. "Energize" is another electronic track, and is one of the only numbers on the album that include English phases ("Put your hands up together, keep your heads up forever, let me sing forever,"). The fifth track "Sparkle" was noted as a club song with an electronic arrangement, similar to the follow-up song "Rollin'". Both tracks feature autotune and vocoder pro-tools, a first for Hamasaki. The album's sixth track, "Green", shows a departure from the album's earlier electronic style; it focuses more on older traditional Japanese sound, alongside instrumentation of electric guitars and drums. The album's third interlude, "Load of the Shugyo", was described as an "atmospheric" number with heavy rock instruments in its composition. Rock music is then influenced on the following tracks "Identity"—a song that discusses about self-confidence—the single "Rule", and the tune "Love 'n' Hate", which talks about the effects of lust. The album's fourth and final interlude "Pieces of Seven" was noted for its "atmospheric" sounds of an ocean, until the second half of the track diverges into a harder rock style. "Days" is the album's first pop ballad, and is described as a love song. It closes with the ballad "Curtain Call", which features a choir and piano riffs throughout its composition.

Question: Question: How many people now live in the city that Moszkowski is from? Passage:He was born in Breslau, Prussia (now the Polish city of Wrocław), into a wealthy Polish-Jewish family whose parents had come to Breslau from Pilica, near Zawiercie, in 1854. He was an ardent Jew at a time when many Jews downplayed their Jewishness. He showed early talent from a very tender age, beginning his musical training at home until 1865, when his family moved to Dresden. There he continued his piano studies at the conservatory. He moved to Berlin in 1869 to continue his studies first at the Julius Stern's Conservatory, where he studied piano with Eduard Franck and composition with Friedrich Kiel, and then at Theodor Kullak's Neue Akademie der Tonkunst, where he studied composition with Richard Wüerst and orchestration with Heinrich Dorn. There he became close friends with the Scharwenka brothers, Xaver and Philipp. In 1871 he accepted Kullak's offer to become a teacher in his academy; as he was also a more than competent violinist, he sometimes played first violin in the orchestra.
